Definition of May and Might
“May” and “might” are modal verbs used to express possibility, permission, polite requests, and suggestions. They belong to a class of auxiliary verbs that add specific meanings to the main verb in a sentence. As modal verbs, they do not change form regardless of the subject and are always followed by the base form of the verb. Understanding their specific functions is key to using them correctly. They often indicate a degree of uncertainty or a conditional aspect to an action or event.
The primary function of “may” and “might” is to indicate possibility. This means they suggest that something is likely to happen or be true, but not with certainty. They can also be used to express permission, particularly in more formal contexts. Additionally, “may” is used to make polite requests, although this usage is becoming less common in modern English. Finally, “might” can be used to offer suggestions, often with a sense of tentativeness. The choice between “may” and “might” can subtly alter the degree of possibility or formality being conveyed.
Structural Breakdown
The basic structure for using “may” and “might” is straightforward:
Subject + May/Might + Base Form of Verb
For example:
- She may go to the party.
- They might arrive late.
To form a negative sentence, “not” is placed after “may” or “might”:
Subject + May/Might + Not + Base Form of Verb
For example:
- He may not attend the meeting.
- We might not finish on time.
To ask a question, the structure is as follows:
May/Might + Subject + Base Form of Verb?
For example:
- May I ask a question?
- Might it rain tomorrow?
When referring to past possibilities, the structure changes to include “have” + past participle:
Subject + May/Might + Have + Past Participle
For example:
- They may have already left.
- She might have forgotten her keys.
Types of Usage
Expressing Possibility
“May” and “might” are frequently used to express that something is possible but not certain. The choice between them often depends on the speaker’s perception of the likelihood of the event.
Generally, “might” suggests a slightly lower probability than “may.”
For example:
- It may rain later today. (There is a reasonable chance of rain.)
- It might rain later today. (There is a smaller chance of rain.)
Granting or Asking for Permission
“May” is used to ask for or grant permission, particularly in formal settings. While “can” is more common in informal contexts, “may” is considered more polite.
For example:
- May I leave the room? (Asking for permission)
- You may leave the room. (Granting permission)
Making Polite Requests
“May” can also be used to make polite requests, although this usage is becoming less frequent. “Could” or “would” are often preferred in modern English.
For example:
- May I have your attention, please? (A formal request)
Making Suggestions
“Might” can be used to make tentative suggestions or offer alternative courses of action. It implies a degree of uncertainty or hesitation.
For example:
- You might want to try a different approach. (A gentle suggestion)

Usage Rules
Present and Future Possibility
“May” and “might” are used to express possibilities in the present or future. While both can be used, “might” often suggests a lower degree of probability or a greater sense of uncertainty.
The tense of the main verb remains in the base form.
For example:
- She may be working late tonight. (Present possibility)
- They might go to Italy next summer. (Future possibility)
Past Possibility
To express a possibility in the past, “may have” or “might have” is used, followed by the past participle of the main verb. This indicates that something could have happened, but you are not certain if it did.
For example:
- He may have missed the train.
- She might have forgotten her appointment.
Formal vs. Informal Contexts
“May” is generally considered more formal than “might.” In very formal situations, such as official requests or announcements, “may” is often preferred. In everyday conversation, “might” is more common when expressing possibility.
Negative Forms: May not and Might not
The negative forms “may not” and “might not” express that something is possibly not true or will possibly not happen. “Might not” again implies a lower probability than “may not.”
For example:
- They may not be able to come to the party.
- It might not rain tomorrow after all.
Common Mistakes
One common mistake is using “may be” and “might be” interchangeably with “maybe.” “May be” and “might be” are verb phrases expressing possibility, while “maybe” is an adverb meaning “perhaps.”
Incorrect: Maybe she is at home.
Correct: She may be at home. or Maybe she is at home.
Another error is using “may” or “might” with another modal verb. Modal verbs cannot be combined.
Incorrect: He may can help you.
Correct: He may be able to help you.
Using the incorrect form of the verb after “may” or “might” is also a common mistake. Remember that modal verbs are always followed by the base form of the verb.
Incorrect: They might went to the store.
Correct: They might go to the store.
Confusing the degree of possibility between “may” and “might” can also lead to miscommunication. While the difference is subtle, “might” generally implies a lower probability.
Incorrect: It might rain today. (when there is a very high chance of rain)
Correct: It may rain today. (when there is a high chance of rain)

May and Might in Subjunctive Mood
In some formal contexts, “may” can be used to express a wish or a hope, often in the subjunctive mood. This is particularly common in fixed expressions.
For example:
- May you have a long and happy life.
- God may forgive you.
Hypothetical Situations

Frequently Asked Questions
Q1: What is the difference between “may” and “might”?
A1: Both “may” and “might” express possibility, but “might” generally suggests a lower degree of probability or a greater sense of uncertainty than “may.” In other words, if you think something is quite likely, you would use “may.” If you think it’s less likely, you would use “might.” The difference can be subtle and context-dependent.
Q2: Can I use “may” and “might” interchangeably?
A2: While they are often interchangeable, especially when expressing possibility, it’s important to consider the nuance of probability. In formal contexts, “may” is often preferred for granting permission.
Also, “might” is more commonly used for tentative suggestions. In many situations, the choice comes down to the speaker’s subjective assessment of the likelihood of an event.
Q3: Is it correct to say “May be I’m wrong”?
A3: No, that is incorrect. “Maybe” is an adverb that means “perhaps,” while “may be” is a verb phrase.
The correct way to express possibility in this case would be “Maybe I’m wrong” or “I may be wrong.”
Q4: Can I use “may” or “might” to talk about the past?
A4: Yes, you can use “may have” or “might have” followed by the past participle to express a possibility in the past. For example, “He may have missed the bus” suggests that it’s possible he missed the bus, but you don’t know for sure.
Q5: Is “may” or “can” more polite when asking for permission?
A5: “May” is generally considered more polite and formal than “can” when asking for permission. While “can” is acceptable in many informal situations, “may” is the preferred choice in more formal settings or when addressing someone in a position of authority.
Q6: What is the negative form of “may” and “might”?
A6: The negative form of “may” is “may not,” and the negative form of “might” is “might not.” These forms express that something is possibly not true or will possibly not happen. Remember that “might not” implies a lower probability than “may not.”
Q7: Can I use “may” or “might” with other modal verbs?
A7: No, you cannot combine modal verbs. It is grammatically incorrect to say things like “He may can help you.” Instead, you would need to rephrase the sentence using “be able to”: “He may be able to help you.”
Q8: How do I use “might” in conditional sentences?
A8: “Might” is often used in conditional sentences to describe hypothetical or unlikely situations. It typically appears in the result clause of the conditional sentence.
For example, “If I had more time, I might learn to play the guitar.”
